Windows & AD Security is Overwhelming.
Let's Fix That.
IT & security professionals are constantly expected to:
- 𝗦𝗼𝗿𝘁 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗲𝗻𝗱𝗹𝗲𝘀𝘀 𝗿𝗲𝘀𝗼𝘂𝗿𝗰𝗲𝘀 — but finding the right ones takes time you don’t have.
- 𝗝𝘂𝗴𝗴𝗹𝗲 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗿𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀 — your company expects you to handle it all.
- 𝗞𝗲𝗲𝗽 𝘂𝗽 𝘄𝗶𝘁𝗵 𝗲𝘃𝗼𝗹𝘃𝗶𝗻𝗴 𝘁𝗵𝗿𝗲𝗮𝘁𝘀 — but attackers move faster than ever.
- 𝗠𝗮𝘀𝘁𝗲𝗿 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 — but where do you even start?
💡 That’s why I created Horizon Secured.
